Abstract (en)
[origin: WO2017015412A1] A virtual machine hosting environment executing on a physical machine is operable to instantiate a virtual machine that is capable of initiating I/O operations directed to a remote storage. The virtual machine hosting environment is operable to determine when an unavailability condition exists with respect to the remote storage and when such unavailability condition no longer exists. The virtual machine hosting environment is further operable to suspend the virtual machine based at least on the determination that the unavailability condition exists and to resume the virtual machine based at least on the determination that the unavailability condition no longer exists. The virtual machine hosting environment may be still further operable to save one or more pending I/O requests generated by the virtual machine in conjunction with pausing the virtual machine and to send the pending I/O request(s) to the remote storage in conjunction with resuming the virtual machine.
